Some background (for writers)

First of all: if you have an idea that you want to roll with, don't let any of this stop you from writing it. These are just some basic guidelines I've thrown together as I go along.
Edit: I wrote the opening thread to be as open as possible. If you have a set of gaming rules or a system that hasn't been written yet, please by all means give it a shot. Everything below is targeted at creating a standard "Fantasy MMORPG" world that you can expand on should you wish. If you want to set the world up a little differently, go right ahead (you can pass it off as a "modded" version of the main game if you'd like to stay "canon"). The idea here is to support interesting/hot storyline's, not to make a perfectly organized game-world.

Second of all: I'd like to thank the CHYOO community for their kind words and feedback. I had no idea this story would be so well received when I started it and I am blessed to have been noticed by some great writers who have helped me expand upon the original idea. I hugely appreciate all their hard work and I encourage anyone reading this to add to what we have created. Thank you and I hope you enjoy your stay.

I've created a forum thread asking which monsters you'd like to see expanded on:

Simon_Silver has made a forum thread asking "Which 'System' makes the tales feel most 'real' to you?": http://forum.chyoa.com/threads/game-monster.316/

Setting:
Medieval fantasy RPG. I'm channeling a lot of the general RPG tropes for writing the plot, or rather I'm poking fun at them. Whenever I imagine the character-sheet of a monster I usually draw on Pokemon's system. I tend to think of it as multiplayer just because then there is no "main character" I have to worry about. The standard setup for classic RPG's is basically this:

1.Country/Village/World is in peril
2.Hero(s) is basically a nobody who is chosen by destiny
3.Hero(s) rampages through hundreds of monsters minding their own business
4.After committing genocide on monster-kind the Hero ultimately saves the world and everyone lives happily ever after

Except the monsters.

This story is about what happens when a monster gets fed up and decides to rebel against convention, using their intelligence (or dumb luck) to break free from their preordained role as a low-level creep and become something greater. I envisioned their goal to be becoming a stronger monster (power is a universal motivator), whether to finally fight back and crush the heroes once and for all or forge a better future for their monster brethren.

Of course, this being CHYOO, a lot of sex will happen one way or the other, that's why people read it. Considering how sexualized most female (and male) characters are in the video game industry it isn't very hard to accommodate that regardless of the story you're writing. While sex could be the focus and driving aspect of your story (it certainly motivates) in my experience it works better when it complements some higher plot.

I'm not being too exact when it comes to breaking the fourth wall or how aware the characters are that they are in a game world, I mostly write whatever I think is funny or advances the plot best. I bring up ideas like leveling and stats for the characters but I also describe the world in a real way (as in, not restricted by the engine of a game). There are some excellent threads people have already written to showcase a good starting thread for a storyline but don't feel limited by their guidelines.

As far as exact world-setting?
Continent/World: Alluvia
As diverse and varied as an RPG map.

Locations (so far):
Ostvale: Jewel of the White Mountains
Large mountain city overlooking the Akarrin desert, renowned for the white stone it's made of. Has changed hands several times through history and is currently under human control. A war between the humans and mountain elves has left the elves scattered throughout the mountains, trying to slowly recover their numbers. The humans of Ostvale look down on them as wild and treacherous.
Origin: Morphworm

Livenvale: An elven starting city.
Origin: Interest in you ((Lesser) Poison Dragon) (I think)

Oscar's Den: Small village that is a common stop on the way out of Livenvale.
Origin: Interest in you ((Lesser) Poison Dragon)

Clearwater Lake:
"Pristine Paradise" - Amorphous Slime, 5/5 stars
"Bleeugh!" - Minor Undead, 4/5 stars
Much sought after spawn point amid a variety of temperate monsters and a favorite out-of-the-way (sometimes literal) stomping ground amongst heroes.
Origin: Amorphous Slime

Griever's Swamp: Once a verdant forest, Griever's Swamp has been overtaken by a corruption that has fouled the air, land, and water. The majority of its "pure" inhabitants left when the corruption came and those that remained behind have suffered the transformative effects of the corruption (as per standard fantasy corruption: males get bigger and more monstrous, females develop enhanced sexual characteristics. Both suffer a "reformed" outlook on life after exposure to the corruption).
Origin: Corrupt Dryad

• Developers note: Players seem to have created a "black market" of sorts with the corrupted materials found in Griever's Swamp, bottling the water and using it on pets or other heroes. Should probably patch that out before they spread corruption everywhere.

Caverns of Kaligoth: Named after the zone's ill tempered boss, the caverns are a winding series of dark tunnels and caves infested with swarms of irritable bats and rats, a few shambling skeletons, a tribe of cannibal Gnomes, and of course the infamous pits of darkness many careless adventurers have stumbled off into their certain demise. It's one of the first real challenges new heroes will go up against, requiring teamwork for proper navigation. It's a large and confusing zone, supplies often run low.
Origin: Treasure Goblin

Gods (so far):
Anari: Goddess of purity, priestesses must be chaste in order to channel her power but they are usually quite strong. Despite her power she is considered by many to be the "little" sister to most of the other gods (however this has been unsubstantiated and many believe the majority of the gods to be approximately the same age). She can be petty and exceptionally vindictive but her healing abilities are second to none.
Approximate Alignment: Lawful Good
Common Avatar: A beautiful golden maiden, wreathed in soft light.

Helia: Goddess of the sun and justice, priests/priestesses use sun/fire magic. She is uncompromising and willful, many city governments hold her as their patron. Despite "seeing" all that the sun touches she is constantly distracted by her brothers Togos and Nalu, much to the appreciation of criminals everywhere.
Approximate Alignment: Lawful Neutral
Common Avatar: The sun or an open flame.

Nalu: God of the moon and reflections, his followers utilize "mirror magic" to confuse, absorb, and reflect enemy attacks. Long ago he stole light from his sister Helia and he has been fleeing from her ever since. A solar eclipse occurs whenever she catches him and the ensuing battle rains chaos down upon the mortal realm.
Approximate Alignment: Chaotic Neutral
Common Avatar: The moon or a thin, pale youth dressed in a white toga.

Logaros: God of controlled magic and knowledge. Patron god for many students of the arcane arts.
Approximate Alignment: True Neutral
Common Avatar: A calm electric blue eye that opens out of midair.

Chitros: God of uncontrolled magic. Patron god of rebels, anarchists, and sorcerers.
Approximate Alignment: Chaotic Evil
Common Avatar: (whispering) A red spark or (speaking) a blood-red explosion caught mid-blast.

Nimrev: God of vermin. Virtually unknown.
Approximate Alignment: ?
Common Avatar: pre-existing vermin.

Lorchos: God of Darkness. Exceedingly powerful and many cults worship him. However he is for the most part ambivalent, abstaining from the mortal plain and only rarely communing with his fellow deities.
Approximate Alignment: True Neutral(?)
Common Avatar: Absolute Darkness.

Togos: God of thieves and deceivers. Patron to the poor and ambitious, Nemesis of the rich and entitled.
Approximate Alignment: Chaotic Neutral
Common Avatar: a rakish young man, jovial and sly.

Vienna: Goddess of the wilds, Patron of savage things, and Caretaker of the Primeval. Literally the wild-child of the gods, Vienna and her cult waged a savage campaign against civilization (and by proxy the other gods) until the other deities united and obliterated her cult on the mortal plane entirely. Thus she suffered the worst fate of a god: to be forgotten.
Approximate Alignment: Chaotic Evil/Neutral (She is utterly uncompromising when it comes to the destruction of civilization, otherwise she might be amiable)
Common Avatar: A cat-eyed amazon clothed in animal skins, a great cat, or a monstrous boar.

Armok: God of blood and sacrifice. Patron of ritual slaughter and Creator of blood magic, he is worshipped by more monsters than heroes.
Approximate Alignment: Lawful Evil
Common Avatar: a towering suit of armor or a seething pool of blood.

Valdur: Elven god of victory and government. Viewed as the "highest" god in many elven conclaves, Valdur is a source of much controversy among the races particularly the elves themselves. In many ways he represents the immortal perfection of elven kind and is often in conflict with Anari, despite being a "lesser" god. At the same time, his critics whisper of dark secrets behind the flawless exterior of Valdur's regime. Outwardly a paragon of purity and elven greatness, rumors persist that he performs perverse acts with his priestesses and ruthlessly destroys those who openly oppose him.
Approximate Alignment: (Supposedly) Lawful Good (but probably) Lawful Evil
Common Avatar: A majestic, pure white unicorn or an tall elven man with white hair, white eyes, and clad in silver armor.

Special Items (so far):
Echo Scarf: Allows intelligent creatures to speak common, regardless of their vocal abilities.
Joss Stick: Cheap sticks of incense to be used as minor sacrificial items, suitable as an offering to any god or goddess (particularly lesser gods).

Monsters (so far):

Weed-Fiend: Dandelion-like flower monster, shoots darts at passing Heroes.

Spider: Generic giant spider enemy. Quite intelligent, usually found in groups. Bites should be treated with anti-venom ASAP.

Imp: Lesser demon, flyer, immune to fire.

Poison Dragon (Lesser): Small, lizard-like dragon enemy. Has a poisonous bite and is more resilient than the average creep but is still a weaker enemy.

Decrepit Armor: Tutorial boss, tough but slow.

Morphworm: More of a joke than an actual enemy, these worms are found in the Ostvale tutorial caves and can morph themselves into various colors/shapes to hide in the environment. They can leech health from an enemy if they can get close enough to touch them.

Baneworm: Small and hideous, Baneworms are easily crushed underfoot by even the weakest heroes. Unless they attack in overwhelming numbers, which they always do. Then they're a squirming nightmare that wants to worm inside any warm, wet environment they can. Many servers ban them.

Amorphous slime: One of the most diverse enemies in the game. Can come in a multitude of sizes, shapes, colors, and even temperatures.

Dryad: Female tree-spirits of the forest, they serve as guardians and shepherds to the plants and animals of the forest, usually non-hostile to good-aligned characters.
Subtype- Corrupted Dryad: One of the few naturally spawning "corrupted" creatures. Like most corrupted creatures, this Dryads original outlook and purpose have been perverted to darker themes than its pure sisters.

Thrall: Half troll, half elf, exceedingly rare because both species hate each other. They are generally about the size and shape of their elven parent, though with considerably more muscle laired on the lithe frame of an elf. Their features tend to be a bit more brutal, or at least fuller, thanks to their troll parent. Most are slaves or outcasts who escaped using their troll-like strength.
Origin: Not Quite... (Gnome-mage)

Rules:

1. Keep it light: there is some leeway with this one but I did intend for this to be a humorous story.
2. Leave the non-game world out of it. Make all the references you want but keep the story in the game, about the Monsters/Heroes....Unless it's really funny.
3. I am far less likely to approve stories that have major grammatical or spelling errors. Missed apostrophes and the occasional slip up are fine but I'm not approving something I can't make sense of.
4. I enjoy crossovers tremendously but if you do write about another authors characters/ideas, try not to change them and get the other authors permission if you plan on making them a major part of your story.
5. ...I can't think of one right now. Write a comment if you want to offer suggestions.
